Definitions

  • the invention is based on a device for fixing fascia holding threads with a sealing cone that can be displaced on a trocar sleeve for open laparoscopy of DE-A-30 11 069, through which a laparoscope can be inserted into the body cavity.
  • the trocar sleeve has at least two advantageously opposing slit clamps for fastening the fascia holding threads and a sealing cone which can be moved longitudinally.
  • This known trocar sleeve with sealing cone has the disadvantage that after insertion into an abdominal wall opening, the trocar sleeve and the sealing cone have a certain position in relation to one another which must not be changed, since the fascia retaining threads firmly connected to the trocar sleeve fix these together with the sealing cone in the abdominal wall opening . It is not possible to change the relative position between the sealing cone and the trocar sleeve, because otherwise the fixation in the abdominal wall opening and thus the gastight seal of the abdominal cavity is abandoned.
  • the object of the invention is to be able to move the trocar sleeve freely into axial positions without inadvertent gas loss in the abdominal cavity, as is required for the procedure.
  • the fixing device is designed so that it can be used both for normal laparoscopy and for trocar sleeves of different diameters.
  • the fixing device On the trocar sleeve 1 provided with a valve is the fixing device, consisting of the sealing cone 2 and the holding plate 4, which have a central channel 3, postponed.
  • the sealing cone 2 is detachably connected to the upper holding plate 4 so that it can also be used for normal laparoscopy.
  • the holding plate 4 according to FIG. 2 is provided with a radial bore for the passage of a sealed axially adjustable push and pull rod 5.
  • a thread engages in the thread of the rod 5 in a transverse bore of a lever 6 which can be pivoted to a limited extent and which is not axially adjustable relative to the rod 5.
  • the rod 5 When the lever 6 is pivoted, the rod 5 is displaced in the direction of the central channel 3 via a compensating element 5a against an interrupted tensioning element 8 loosely inserted in a flat annular recess 7 in the holding plate 4, by means of which the free lumen is reduced by a certain amount, so that thereby the fixing device 2.4 on the trocar sleeve 1 can be easily and conveniently ascertained and released.
  • Clamping devices 9 are provided at several points on the holding plate 4 for fixing fascia holding threads, by means of which the fixing device 2, 4 is held in a fixed position relative to the abdominal wall.
  • the clamping devices 9 for the fascia holding threads consist of a bearing block 10, in which a rotatable shaft 11 is mounted, which according to FIG. 2 is designed with a rotating handle 12 on one side of the bearing block and eccentrically on the other side or is provided with an eccentric 13, whose peripheral surface is roughened or profiled. Between the peripheral surface of the eccentric 13 and the surface 14 of the holding plate 4 facing it, the ends of the fascia holding threads are passed through and then by twisting of the eccentric clamped by means of the handle 12 continuously getting stronger. In the open position, the position of the eccentric 13 is fixed, for example, by latching and an engaging spring-loaded ball.
  • the arrangement described above makes it possible to fix the fixation device easily and conveniently in the abdominal wall opening by means of the fascia holding threads.
  • the doctor is now able to move the trocar sleeve in the axial direction through the fixing device in order to achieve any other required positions of the trocar sleeve.
  • the fixing device itself remains unchanged in its fixed position due to the fascia holding threads.
  • the fixing device 2, 4 is otherwise sealed against the trocar sleeve 1 by a sealing element 15, which is held in place by a screw-on cap 16 via a pressure ring 7.
  • the sealing element 15 with the pressure ring 17 is removed after the cap 16 has been loosened, and a reducing sleeve 18, 19, which restricts the passage of the fixing device, is inserted into the central channel 3 the screw cap 16 is fixed ( Figure 3).
  • This sleeve 18, 19 has at its upper end an extension which replaces the pressure ring 17.
  • the clamping ring 8 is loosely fixed in the reducing sleeve 18 by means of the cylinder sleeve 19.
  • the central channel 3 of the fixing device 2, 4 or the reducing sleeve 18, 19 is closed at the top by a sealing element 15 or a rubber cap 20 with a central passage, the sealing edge of which lies against the trocar sleeve 1 and the escape of gases from the Abdominal cavity prevented.
